    Chlorophyll naturally fluoresces in red under uv light, so you can try it with any plant it should work. We use this property in biology to spot the chloroplasts in plant cells

    Anyone know what kind of plant that was that glowed so red? I wonder if different plants glow different colors and if anyone made a vivarium with that in mind.

    you should stick with just coco fiber if you are worried about mold. Potting soil will have mold spores in it 100% of the time and contains nutrients that the mold will feed on.

    UV light is stressful for scorpions and can even cause death. Make sure your black light doesn’t have UV in it if you use it to find them often

    Do you know that exactly shining black light or ultraviolet on glowing scorpions does enormously harm them when prolonged ? In scorpions, exposure to ultraviolet light can cause blindness, stress, and even death. Prolonged exposure to ultraviolet light also lessens the intensity of their fluorescent glow. So, if you are raising scorpions, it’s important to keep them out of prolonged direct sunlight as well as UV light although it it is cool to see them glow.

    I might be wrong but I think that little plant that glows red is called Peperomia rotundifolia, the common name is jade necklace. Pretty popular in terrariums I think

  • Dark Luna

    I'm gonna be that person, but the first plant you put in there is a major drama queen and won't survive in that setting unless you can keep it at high humidity. 😅 but it will totally let you know when it needs water and look like its dying. Give it some h20 and it will perk back up. Otherwise it looks great ☺️

    couldnt you make some railings on the ceiling and from them you hang a plate of corkbark (like a square plate) and then you can put art on both sides and slide it to the wall and away from the wall and add other "layers" ? that way you could keep more fanmail/art up but save some space
